Abstract: A circuit unit is provided in which it is possible to connect circuit board to a terminal using a simple operation without removing a passivation film from above the terminal. A metal electrode which conducts with a circuit element is formed above a substrate. Multiple column shaped insulation films are each formed at a uniform pitch in two intersecting directions above the surface of the metal electrode. A metal electrode is formed above the metal electrode including the insulation film. A passivation film is formed on a surface of the metal electrode. Conductive beads are stuck between pairs of projection structured bodies formed on a surface of the passivation film, the passivation film on a side surface of the projection structure is scraped whereby the conductive beads conduct simultaneously with the metal electrode and an electrode formed on the circuit board.

Abstract: An organic display device includes a pixel driving circuit having a thin film transistor connected to a current supply line and a capacitor. A first insulation layer, with a first electrode thereon, covers a source electrode of the transistor. The first electrode is connected to the transistor through a contact hole in the insulation layer. A second insulation layer including an aperture is formed on the first insulation layer and electrode layers. An organic light emitting layer, with a second electrode thereon is formed in the aperture and connected to the first electrode. The second insulation layer includes an inner wall at the aperture, said inner wall having a surface of a convex plane on an edge of the recessed part of the first electrode. The convex plane is located between the organic light emitting layer and the edge of the first electrode, and the second electrode is formed over plurality of pixels.

Abstract: A display device includes: a resin layer on the circuit layer including a groove surrounding and separating a display area; light-emitting elements on an upper surface of the resin layer so as to emit light with luminances controlled by the currents; a sealing layer covering the light-emitting elements; a second substrate above the sealing layer; a sealing material provided between the sealing layer and the second substrate so as to surround the display area and the groove; and a filling layer surrounded by the sealing material between the sealing layer and the second substrate. The groove is formed along a line describing a shape that is inscribed in a rectangle and not in contact with corners of the rectangle as viewed in a direction vertical to the upper surface of the resin layer.
